I've used this logo for several years on this site. Originally my plan was to offer website design services for healers and spiritually oriented teachers, and it was in that context this logo was designed.
The idea conveyed is the types of communication that have been used over the millenia. Originally we just talked to one another, and then we developed smoke signals, and then we developed writing, and writing developed into typewriters and finally into computers. It's all about people connecting with one another and communicating their ideas.
What will come after computers? Who knows, but one thing is clear is that technology will not stand still, and technology will come up with further refinements to human-human communications.
